Choosing an Electrical Switch

Switch Shown Mounted

Switch

Built into a terminal block, these switches mount to DIN rail. They can be mounted side-by side.

Switches with maintained/momentary switch action stay switched from one side and spring back from the other side.

Switches with an on-on or on-(on) position designation alternate power between sets of terminals.

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.

Panel-Mount Disconnect Switches

Install these switches in a panel cutout. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All are UL listed, C-UL listed, and CE marked—they meet American, Canadian, and European safety standards.

Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).

Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

Terminal covers prevent contact with live terminals.

Enclosure Disconnect Switches

Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door. Cut the shaft to fit the enclosure. Use a padlock (not included) to lock switches in the off position. Mount to DIN rail inside an enclosure; mounting depth is the distance from the panel door to the DIN rail. UL listed, C-UL listed, and CE marked, these switches meet American, Canadian, and European safety standards.

Use optional sealing gaskets in washdown environments; they create an IP65 rated seal around the actuator.

Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

Add junction blocks to connect a ground wire.

Terminal covers prevent contact with live terminals.
