DT-2RS1-A7

Snap Action, Limit Switches often appear in commercial, residential and industrial control systems, they are broadly used to monitor the motion and position of materials, equipment, and other mechanisms. The DT-2RS1-A7 snap switch is a 3 amp SPST, 1NO-1NC recoverable snap action limit switch with a self-locking lever actuator.

Overview

The DT-2RS1-A7 is an UL recognized component and VDE, CCC and CE registered. It has a reliable snap action mechanism and is available in five types of actuator : roller plunger, pin plunger, side rotate, straight-lever, and hook-lever. The contact rating is 3A/125 VAC, 3A/30 VDC; and its electrical life is 30,000 cycles. The cover and base are black high-temperature UL 94 V-2 plastics and the actuating plunger is made of zinc-plated steel. The terminals of the DT-2RS1-A7 can be soldered, screwed or crimped to fit. The switch is IP67 rated and offers IP20 level of protection – making it dustproof, waterproof and shockproof.

Applications

The DT-2RS1-A7 is used in a variety of applications requiring precision limit switching, such as appliances, lighting control systems, industrial machinery, robotics, and assembly control systems. It can be used for many other purposes as well, such as: on/off switching, over/under voltage protection, motor control, safety detection, motor start/stop control, and timer areas.

Working Principle

The DT-2RS1-A7 is a normally open (NO) snap switch, which means that the switch opens when the circuit is inactive, and closes when the switch is actuated. The switch has a snap-action mechanism so that when it is actuated, the contact changes state quickly and with a distinct “click”. This snap-action contacts reduces the likelihood of arcing and premature aging of the switch. The switch is actuated by a plunger, roller, lever, or other mechanical device, and when the limit has been reached, the contact opens or closes for switching.

Conclusion

In conclusion, the DT-2RS1-A7 is a versatile and reliable snap-action limit switch ideally suited for a range of applications. It is UL recognized, VDE, CCC and CE registered, providing users with increased safety and reliability, and can be used in applications requiring precision limit switching, such as appliances, lighting control systems, industrial machinery, robotics, and assembly control systems. The DT-2RS1-A7 is dustproof, waterproof and shockproof and is IP67 rated, offering users the highest levels of protection.
