Choosing an Electrical Switch

22 mm Panel-Mount Build-Your-Own Plastic Switches

Choose an actuator and contact block to make your own switch. All actuators are rated NEMA 4X and 13 for protection from corrosion and oil/coolant spraying, and IP rated to withstand washdowns. Use legend plates (not included) to label switches.

Padlockable covers prevent unauthorized use.

Heavy Duty Covers for Push-Button Switches

Made of stainless steel, these covers offer more protection than rubber covers. Use them in place of panel mounting nuts to protect push-button switches from impact, moisture, and dust.

Two-Hand Safety Switches

It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. A complete system requires two switches, one safety relay, and two outlet boxes.

Switches meet OSHA requirements and ANSI standards for machine operator safety. They're rated IP64 for protection from splashing water.

Safety relays control the two switches by sending an output signal when both switches are activated within 0.5 seconds of each other. Self-monitoring circuitry offers additional protection—if any part of the system fails, the entire system shuts down until repaired.

Outlet boxes have a drilled hole to fit the switch.

Switch guards protect switches against damage and accidental activation. Use one guard per switch.

Push Button Safety Covers

Lock out the on/off or emergency-stop buttons on machinery to prevent accidental or unauthorized startups, such as during maintenance. Install these covers over the buttons and use a padlock to temporarily deny access to them. The locked covers let workers know the equipment is off for safety.

To comply with OSHA 1910.147 lockout requirements for maintaining machinery, you must cut off the electricity at the circuit in addition to disabling the push button.

Removable covers twist on and off a mounted base that fits around a button. The included labels help you identify the buttons.

Hinged covers have a door that you can flip open for access to the button when the lockout is complete. These covers fit 22 mm buttons; snap off the tabs around the mounting hole to fit 30 mm buttons.

Often used with emergency-stop buttons, crossbar covers have a bar that locks a button in the off position.
