D22015P

Toggle switches are extremely common in a variety of electrical applications ranging from the homes of everyday consumers to the laboratories of the professional engineer. And the application field and working principle of one type of toggle switch--D22015P toggle switch can be expounded as follows.

Features

The D22015P toggle switch series is a SPST Single-pole/single-throw type switch design for low-level switching applications including low voltage circuits, radios, and small appliances. This D22015P toggle switch offers characterized toggle handle movement for high reliability and has a long electrical life of 50,000 cycles. The D22015P features an ergonomic designed bat handle, giving the user a positive feeling when lever is engaged or disengaged. Illuminated models feature LED illumination powered by a self-contained battery source.

Applications

D22015P toggle switches offer a highly reliable choice in applications including communication interface and control, medical equipment, security systems, aerospace and military electronics and automotive control systems. The base model of the switch is also suitable for small to medium lighting controls.

Working Principle

The basic working principle of a toggle switch is simple. When the switch is in the OFF position, the two terminals are disconnected. When the switch is in the ON position, the two terminals are connected. Toggle switches have a handle that will physically rotate when pushed or pulled. This rotates a short-arm lever that touches and completes the circuit, thus allowing electricity to flow between the two terminals to power the device.

Construction

The D22015P toggle switch series are traditionally constructed with a knob-style lever switch that rotates a short-arm lever. The terminations options include solder, straight and right angle PC pins. The design of the switches are compact and require minimal panel space, reducing the chance of damage in high vibration applications.
