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.

Combine an actuator and a switch to assemble the exact limit switch you need. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used for conveyor systems and elevators. Each actuator style is compatible with all housing styles and vice versa.

Switches with a polypropylene plastic housing are lighter in weight than metal switches.

Switches with an LED power indicator and LED status indicator show you the status of the line and load phases. They give you extra assurance that your switch is connected and wired correctly.

IP65 switches protect against dust and splashing water. IP66 switches protect against dust and washdowns. IP67 switches protect against dust and temporary submersion.

Replace the hinges on access doors or machine guards with these switches to keep your team safe from active machinery. Also known as interlock switches, they automatically shut off power to your machinery when the door or guard opens. They can be mounted on flat frames or aluminum T-slotted framing. These switches have positive-force, normally-closed contacts that will open a circuit when the switch is actuated, even if a spring fails or the contacts stick. They’re rated IP65 for protection from washdowns.
