Each series of TER limit switch offered by Crane-Controls.com feature die-cast alloy enclosures, covers and switch-heads with weather-proof gaskets used at every joint. Switch contact points are made of Silver-alloy material, specially designed to facilitate strong starting currents. 

 

 

Mechanical switch operation for quick-break types is instantaneous and not determined by the strength of external control action. For slow-break limit switches control input is transferred as a direct pressure on the moving part of the contacts so break time is directly related to speed of control input, More information limit switches can be found here.
