Snap action switches, also called limit switches, provide dependable and precise operation at a low cost. The AM50030D33-A is part of a line of snap action switches that are used in a variety of applications. This article will explain the application fields and working principle of the AM50030D33-A.

Application Field

The AM50030D33-A is a snap action, limit switch designed to provide reliable performance in light to medium duty applications. It is commonly used to sense movement of a mechanism or limit its travel. The switch is designed with a wide range of adjustable or replaceable operating heads and sealed actuators, that make it suitable for applications where water, oil or dust exposure. The exposed actuator models make it suitable for applications where contact with the operating surface is desired.

The AM50030D33-A also features two sets of single pole double throw (SPDT) contact assembly for a maximum of four (4) contact. This allows the device to be used in applications that require multiple sensing points. It is UL, CSA, CE and RoHS approved and meets relevant standards for use in a variety of application fields such as home appliances, HVAC, office automation, and industrial controls.

Working Principle

The AM50030D33-A features a snap action switch with a rectangular plunger. The plunger can be actuated with a simple push and will then switch the circuits on or off. When the plunger is pushed, it activates a spring loaded mechanism that causes the switch to snap into position, opening or closing an internal switch and either making or breaking electrical contact. The contacts in the switch are located at the internal end, which is protected by a weatherproof seal to prevent corrosion.

The operating temperature range of the AM50030D33-A is -25°C to 70°C, with a 660V maximum working voltage. The switch is designed with a dielectric strength of 1,000V and a 5,000V dielectric strength test. The device features a mechanical lifespan of 200,000 cycles and a contact current rating of 10A.

Overall, the AM50030D33-A is a reliable, cost-effective snap action, limit switch suitable for a variety of applications. It is designed with a wide range of adjustable, replaceable operating heads and sealed actuators that make it suitable for applications where contact with the operating surface is desired. The device also features two sets of single Pole double throw contacts and a high dielectric strength, making it suitable for medium-duty applications.
