ABS1110509

Snap Action, Limit Switches

The ABS1110509 snap action, limit switch from Dwyer Instruments is a versatile and reliable switch for industrial applications. This snap action switch is designed for long and short cycles depending on the user\'s needs. It is ideal for applications such as fluid level sensor for liquid tanks, light switches, conveyor switch, and other general applications in harsh industrial environments.

The key components of the ABS1110509 limit switch are the outer housing and plunger assembly. The enclosure case is constructed from rugged and durable aluminum alloy body with a chrome plated face. This combination ensures that this switch is highly resistant to shock and vibration while still remaining lightweight and easy to install.

The plunger assembly consists of a stainless steel shaft that passes through a threaded hole in the side of the housing. A compression spring sits between the plunger and the body allowing the plunger to be easily adjusted and locked into place. The plunger is then pressed against the bushing and moves the contact assembly inside the switch agreeing to the desired position.

The ABS1110509 snap action, limit switch consists of two contact assemblies that are held in place by plastic clips. Each contact consists of a silver alloy contact which is connected to a copper buss bar. These bars connect the contact assembly to the body of the switch, so when one of the contacts is pushed by the plunger, it moves the opposite contact, thus completing the circuit.

The ABS1110509 snap action, limit switch is hygroscopic, meaning that it gradually absorbs moisture from its environment. To protect the switch from prolonged exposure to moisture, it is necessary to apply a thin film of dielectric silicone grease or Vaseline to the contacts and the plunger assembly. This helps to insulate the contacts and prevents corrosion.

Different versions of the ABS1110509 are used in a variety of applications, such as conveyor systems, elevators, door openers, motor controllers, machinery controllers, security systems, brakes, overload protection and other industrial applications. The switch can be used in temperatures between -40 °C (-40 °F) to +40 °C (104 °F).

The ABS1110509 snap action, limit switch is an excellent choice for industrial applications. It is easy to install, highly reliable and versatile, and provides a safe and secure operation in any weather condition.
