12SE7

Snap action, limit switches are mechanical switches which for example close a circuit when a presence sensor is activated or a certain amount of pressure is applied to a dielectric surface. They are often used in industrial applications to indicate whether a certain pressure or heat level has been reached, for example when a certain temperature needs to be maintained. The 12SE7 is one type of snap action, limit switch which is commonly used.The 12SE7 is a normally closed, momentary contact switch. It is insensitive to normal shock, vibration and temperature variations, making it suitable for a variety of industrial settings. The switch can be mounted in series with a relay switch of the correct rating, to allow electrical control of the switch.The 12SE7 consists of a stationary base frame, an actuator contact blade, an armature spring contact, and a stationary actuator pin, all contained in a plastic housing. When the contact pins are moved to the closed position, they form a bridge across the switch and make contact with the contacts on the frame. The armature spring contact is positioned in such a way that it forces the contact pins together when pressure is applied to the actuator. When the pressure is released, the armature spring contact forces the contact pins apart. This forces a momentary contact closure, and is why the switch is referred to as a momentary contact switch.The 12SE7 is often used in applications where a brief or momentary contact closure is required. It is a reliable switch and is suitable for applications where other mechanical switches may not perform well. It is also an inexpensive switch, making it a cost-effective choice for applications where the total cost of ownership needs to be low.The 12SE7 also offers reliability and long-term operation. The contact points are made of hard metals, so they are resistant to wear and tear and have a long service life. The switch is also resistant to temperature variations, so it can be used in temperature-sensitive applications. The switch can usually withstand extremely high and low temperatures without failure.Overall, the 12SE7 is a reliable and affordable snap action, limit switch, making it suitable for a variety of industrial applications. Its hard metals contact points and temperature resistance make it ideal for applications where reliability and long-term service life are critical. The 12SE7 also offers a momentary contact closure, making it ideal for applications where a short duration of contact closure is required.
