Economy Vacuum Switches

Choose these switches when you need reliable switching but not high accuracy. When they reach a set vacuum, they turn equipment on and off, signal automatic controls, or trigger alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). All meet American and European safety standards since they're UL recognized components and CE marked.

Tilt Switches

Style A

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. All combine electromechanical and solid state technologies for reliability and long life.

Differential Angle—Differential angle is the total angle from the point of activation to the point of deactivation.

Economy Pressure Switches

Use these switches for applications that need reliable switching but don’t require high accuracy. When a set pressure is reached, they turn equipment on and off, signal automatic controls, or trigger alarms. These are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). All meet safety standards.
