contactor

/ˈkɑntæktɚ/ noun

A relay used to control an electrical power circuit

Word Origin Contactor is a device that makes or breaks an electrical contact, and it comes from Latin 'contingere' (to touch together), from con- 'together' and 'tangere' 'to touch'. The breakdown con+tact+or shows the root tact- (touch) and the agent suffix -or. The same root gives us contact, tactile, tangible, and tangent. The PIE root *tag- 'to touch' also yields intact (untouched) and contingent (touching upon).
