Switch Contact Blocks

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.

30 mm Panel-Mount Push-Button-Actuator Emergency Stop 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.

Aluminum Enclosed Push-Button Switches

A lightweight yet durable alternative to stainless steel enclosed switches, these aluminum enclosed switches withstand corrosion, oil, and washdowns. They can mount directly to a wall when there’s not enough room in an electrical panel. The enclosure has knockouts so you can easily connect it to conduit fittings and cord grips.

Joystick Switches

Intuitively steer and position cranes, robot arms, and other machinery that moves in multiple directions—your equipment will follow the movements you make with these joysticks. They control multiple circuits as you move them in different directions and patterns. Assemble a complete switch with an actuator and at least one contact block (sold separately).

Actuators

Image of Product. Front orientation. Joystick Switches.

All actuators include a mounting clip that can fit up to two contact blocks. They’re NEMA and IP rated for protection from dust, washdowns, and oil/coolant spraying.

2 Positions—Two-position actuators require one to four contact blocks.

4 Positions—Four-position actuators require two to four contact blocks. They are off in the center position.

Momentary Switch—Momentary actuators can only be locked in the off position.

Maintained Switch—Maintained actuators can be locked in any position.

Chrome-Plated Steel—Chrome-plated steel actuators resist wear better than rubber actuators.
