Handle Push-Button Switches
Save space in your setup—these switches double as handles on machines and equipment. Grab the handle and trigger the push-button to open the door and activate the switch in one motion. They’re often used on cages surrounding robotics.
Switches with status indicators alert you when a switch has been actuated.
Add a matching handle without a switch to keep door pulls uniform.

Push-Pull Switches
The lever sticks out further than a push button, making it easy to identify the position of these switches. They're often used in marine environments.
Switches with a sealed body provide extra protection from moisture and dirt.
Three-position switches close one contact when pulled to the middle position, and close two contacts when pulled all the way.

Tilt Switches
Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. Differential angle is the total angle from the point of activation to the point of deactivation. All combine electromechanical and solid state technologies for reliability and long life.

Potentiometers
Vary electrical flow to control speed, volume, and light intensity. The number of turns affects the resolution—the higher the number, the better the control. Also known as variable output switches. A knob is required (not included).

Stud-Terminal Relays
These relays are suitable for DC-powered equipment such as forklifts, floor scrubbers, and trucks. They are rated for continuous operation for cycles that run longer than 30 seconds.
3-terminal relays require the same input and switching voltage. 4- and 6-terminal relays allow different input and switching voltages.

Weatherproof High-Starting-Current Vehicle Relays
Crimp-On
Terminals
An extended housing shields the terminals on these relays from weather. They're also rated IP54—when they're plugged into the relay socket, they're sealed to keep splashing water, like rain, from getting inside. They handle high starting (inrush) currents that often occur when turning on a vehicle. To prevent damage to sensitive equipment, these relays will partially suppress a momentary surge in voltage when the relay switches off. They’ll take a voltage spike of 300V to 500V and bring it down to 100V.
Relays for surface mounting have a tab for added security in high-vibration applications.

These relays handle the high starting (inrush) currents that often occur when turning on a vehicle. Also known as ISO relays, their blade terminals meet ISO 8092-1 dimensional standards to fit in road vehicles for easy maintenance and repair.
Relays for surface mounting have a tab for added security in high-vibration applications.
Relays with surge suppression coverage prevent damage to sensitive equipment by reducing the 300V to 500V spike that happens when you switch relays off. Relays with partial surge suppression coverage bring this spike down to 100V. Relays with full surge suppression coverage eliminate the voltage spike.
Relays with dual output let you control two separate loads or circuits independently. For example, in a car window, these relays could control it moving up and down.

Solid State High-Starting-Current Vehicle Relays
Crimp-On
Terminals
With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter than mechanical relays. They can handle high starting (inrush) currents. The blade terminals meet ISO 8092-1 dimensions, ensuring they are compatible with the electrical connections in road vehicles you need to maintain or repair. Also known as ISO relays or automotive relays.
