AVM3455P-A

Snapt action switches, also known as limit switches, are essential components of automated systems, from simple industrial control devices to high-level automation systems. AVM3455P-A is a subminiature snapt action switch of normally open type, widely used in automation systems for position detection, and limit protection. As an important part of automation systems, the application field and working principle of AVM3455P-A are described in detail below.

Application Field

1. AVM3455P-A snapt action switches are mainly used in motor industry, air conditioning industry, home automation, elevator industry and automotive industry etc.

2. It can be used to detect pressure, open/close of doors and windows, status of machines and different buttons of instruments.

3. It also widely used in home appliances with the functions of overload protection and parameter setting.

Working Principle

AVM3455P-A snapt action limit switches works when the actuator is pressed, turned or moved and is triggered by magnetism. It has low energy consumption, small size and durable working capability. When pressing the actuator, the contact element actuates the sensing device to open and close the contacts. Once the actuator is pressed and released, the switch will automatically return to its original position.

AVM3455P-A is mainly composed of four parts, namely the housing, contact element, actuator and sensing element. The sensing element used in this switch is an electrical magnetic spring. When the actuator is pressed, the spring will open or close the contacts to cut off or connect the circuit. The contact element itself is a built-in cantilever beam to form a contact opening and closing process.

With its low power consumption, small size, high reliability and durability, AVM3455P-A is a perfect choice for use in automation systems with intermittent motion requirements.
