MICRO SWITCH Specialty Large Basic Switches 004956 BS DT MN MT TB Series Issue 3 Datasheet 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 Metal or plastic enclosures available to prevent contact with DESCRIPTION switch terminals MICRO SWITCH premium specialty large snap-action Select switch series with a temperature range of switches are designed for repeatability and enhanced life. -55 C to 85 C -67 F to 185 F These series of precision switches feature application-specific Agency certifications with CSA and UL for select catalog characteristics. From double-break circuitry to handling power listings duty electrical loads, MICRO SWITCH premium large snap- MIL-PRF-8805 for select DT Series catalog listings action switches are suitable for a variety of applications. BS Series switches offer alternatives to solve challenging switch POTENTIAL APPLICATIONS applications. These unique solutions can provide adjustable Temperature and pressure switch assemblies operating characteristics, sequential outputs, or impact Motor and solenoid dc control circuits actuation (no external plunger). Welder control circuits DT Series switches consist of two independent single-pole Switch element in machine tools double throw (SPDT) contacts in one housing controlled by an Switch element in manually operated devices integral common actuator. The DPDT contact configuration provides a contact for the control circuit and a different contact VALUE TO CUSTOMERS for the signal or auxiliary circuit. Can control two independent circuits in a small package (DT MT Series magnetic blow-out switches are designed to switch Series and TB Series) high-capacity (125 Vdc/250 Vdc) electrical loads. An integral Unique switch design with adjustable operating characteristics magnet around the contact gap deflects the arc away from the (BS Series) contacts, extending switch life. Vents between the cover and Magnetic blow-out contact design permits control of dc housing allow the hot gas to escape. circuits in a small package size (MT Series) Easy to gang mount, MN Series single pole double throw Double break switch design adds element of redundancy double-break switches are for use with limit or control within small switch package (MN series and TB Series) mechanisms on machine tools, presses, or other equipment.
