Honeywell Premium Basic Switches - DT and MT Series
The Honeywell premium large snap-action micro switches series are designed for repeatability and enhanced life. These series of precision switches feature application specific characteristics, from double-break circuitry to handling power duty electrical loads. DT Series switches consist of two independent single-pole double throw contacts in one housing controlled by an integral common actuator. The DPDT contact configuration provides a contact for the control circuit and a different contact for the signal or auxiliary circuit. MT Series magnetic blow-out switches are designed to switch high-capacity electrical loads. An integral magnet around the contact gap deflects the arc away from the contacts, extending switch life. Vents between the cover and housing allow the hot gas to escape.
