Contacts

The 90151-AS, commonly known as an Interrupt Contact, is a rugged and reliable electrical contact that provides switching and interruption of electrical signals. It is widely used in the automotive industry for door locks, window mechanisms, and powertrain control modules. The Interrupt Contact utilizes two stationary contacts, which are connected via a pivoting arm. The movable arm is biased by a spring, which helps keep the contacts closed when the mechanism is not activated. When a force is applied to the lever arm, such as a switch manipulation, the contacts open and the current flow is now interrupted.

Spring Loaded and Pressure

The 90151-AS also utilizes two spring-loaded contacts which are actuated by an external force. The spring-loaded contacts can be manipulated by a switch, a push button, or any other mechanism that applies pressure. Once the pressure is applied, the contacts open and the electrical flow is interrupted. The pressure required for activation is adjustable and depends on the design of the contacts. For some applications, the external force can be replaced with an actuator of some sort. This type of operation is known as a vacuum switch, where a vacuum is applied to the contacts in order to open them.

The 90151-AS can also be used in an alternating current application, where the current is switched from one line to another via an external mechanism. This type of application is called a dual-pole switch and is commonly used in low voltage applications, such as computers or phones.

The 90151-AS is an extremely reliable and robust electrical contact with a wide range of uses. It is frequently found in the automotive industry, but is also found in other applications, such as computers and electronics. Its compact size and adjustable pressure requirements allow for precise switching and interruption of signals when needed.
