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.
