Honeywell’s MICRO SWITCH BS | DT | MN | MT | TB Series - Specialty Large Basic Switches: MICRO SWITCH™ premium specialty large snap-action switches 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, MICRO SWITCH™ premium large snapaction switches are suitable for a variety of applications. BS Series switches offer alternatives to solve challenging switch applications. These unique solutions can provide adjustable operating characteristics, sequential outputs, or impact actuation (no external plunger). DT Series switches consist of two independent single-pole double throw (SPDT) 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 (125 Vdc/250 Vdc) 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. Easy to gang mount, MN Series single pole double throw double-break switches are for use with limit or control mechanisms on machine tools, presses, or other equipment. MICRO SWITCH™ TB Series miniature single pole double throw double break switches offer a means of controlling circuits similar to the MN Series switches except in a smaller package. Features:

Double pole design in small package allows for control of two independent circuits (DT Series and MN Series)

Switch design with adjustable operating characteristics (BS Series)

Higher dc current capacity at 125 Vdc and 250 Vdc with magnetic blow-out contact design (MT Series)

Compact switch package with double-break contacts (MN Series and TB Series)

Variety of integral plunger and lever options or auxiliary plunger and lever options

Most switches mount on the common 25,4 mm [1.00 in] centers
