Choosing an Electrical Switch

Sequenced Latching Relays
These relays switch through a series of different circuit configurations every time they receive an input voltage. The input voltage latches them in position, so they don’t require a constant voltage to stay switched. Use them to control motors, pumps, and lighting. The covered terminals prevent contact with live connections. Mount to 35 mm DIN rail. Also known as step relays.

Two-Hand Safety Switches
It takes two hands to activate these switches, minimizing the risk of accidental equipment start up. They have an emergency stop push-button to immediately cut power. They’re rated IP65 for protection from low-pressure washdowns.
Switches with push-button actuators require a safety relay (sold separately) for a complete system.
Switches with finger-touch actuators turn circuits on and off with a light touch, even when wearing gloves. An infrared sensor detects the lightest finger contact, and an indicator lights up to confirm when they are activated. Because they don't require you to press down a button to operate, they meet ANSI B11.TR1 standards to reduce hand, wrist, and arm fatigue. You'll need a relay or controller to complete your system—upgrade to a controller if you plan to operate additional devices beyond your switch.
Safety controller expansion modules can be added to safety controllers to increase the number of inputs.
Telescoping stands can be added to switches with finger-touch actuators to mount them away from a wall. The stands telescope to adjust the height of the switch and tilt to adjust the angle of the switch.
