Choosing an Electrical Switch
More
Contact Blocks for Manual Switches
Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

22 mm Panel-Mount Build-Your-Own Plastic Switches
Choose an actuator and contact block to make your own switch. Actuators are rated NEMA 3S, 4X and 13 for protection from dust, outdoor environments, corrosion, oil, and washdowns. They mount into standard panel cutouts. Use legend plates (not included) to label switches. BACO Controls switches are only compatible with BACO manufactured legend plates.
Contact blocks with mounting latch accept additional contact blocks to control more circuits.

Metal 22 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches meet EN 418 for compliance with European machine directives for emergency stop applications. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They include enough contact blocks to control the number of circuits listed.
Pull reset, illuminated pull reset, and turn reset switches are rated NEMA 4, 13, and IP66. Contact blocks for these switches are rated IP20.
Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

Vibration-Resistant Plastic 22 mm Emergency
Stop Panel-Mount Push-Button Switches
A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications. These switches immediately cut power with a single push. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. These switches meet American, Canadian, European, and other global safety requirements. They’re rated NEMA 4X, NEMA 13, and IP65 for protection from corrosion, washdowns, and oil/coolant spraying.
Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Continuously illuminated switches stay lit once installed for high visibility in dark areas.

Plastic 22 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches meet EN 418 for compliance with European machine directives for emergency stop applications. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They're rated IP66, IP69K, NEMA 3S, NEMA 4X, and NEMA 13, and are UL and C-UL Recognized Components. Switches include enough contact blocks to control the number of circuits listed. Contact blocks are rated IP20 and are UL and C-UL Listed.
Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.
Additional contact blocks (sold separately) can be added to control more circuits, or replace the included contact block.

Hazardous Location 30 mm Panel-Mount Push-Button Switches
Actuate these switches with a quick push. A housing seals in anything that could ignite flammable material, so you can use them where ignitable gas and dust may be present. You’ll know they’re safe because they meet NEC Class I Div. 2, Groups B, C, D for hazardous locations. Install them in a standard panel cutout.
Mushroom switches have a button that sticks out from the panel. Because they’re easy to identify and actuate, these switches are often used to stop equipment. They have a twist reset, so they’ll return to their starting position when you rotate the button.
Switches come with a contact block for each number of circuits they control. Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.

30 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches are rated for protection from low-pressure streams of water and oil/coolant spraying. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. Mount them in a standard panel cutout.
Illuminated switches are visible in low light. They include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Turn twist switches back on by twisting the button and pull switches by pulling it. Add an optional lockout (sold separately) on either kind to cover the button and prevent changes to its position.
Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact blocks.
