The 404EN64-6 is a type of snap action, limit switch from Grayhill, Inc. It is a rugged, field-adjustable switch which features a low-profile, wraparound terminal block for easy installation and maintenance. The switch has two movable contact elements that are actuated by an external force. When an external force is applied, the contacts open or close depending on the actuation direction. The 404EN64-6 is an On-Off-Momentary switch with a single-pole, double-throw (SPDT) configuration. This means that it has two sets of contacts that are opened and closed by a single actuation.

The 404EN64-6 is suitable for a wide range of applications, such as controlling electrical Motions, operating alarms, and momentary actuation of relays, solenoids and other electrical devices. This switch is also well suited for a variety of industrial, transportation and security applications, as it is designed to operate reliably in harsh environment conditions including extreme temperatures, moisture and shock. Additionally, it is ideal for use in electrical enclosures and industrial control panels, due to its adjustable actuation force and snap action mechanism.

The working principle of the 404EN64-6 is quite straightforward. When an external force is applied to the switch, a mechanical energy is generated which causes the contacts to open or close. The opening and closing operation occurs when the external force is greater than the actuation force, which is adjustable and can be set anywhere between 0.5 and 3.5 N. This ensures that the switch is actuated with a minimal amount of effort. Additionally, it is equipped with a snap-action mechanism to minimize the possibility of accidental contact closure.

In conclusion, the 404EN64-6 is a snap action limit switch from Grayhill, Inc. It has a low-profile, adjustable-force mechanism for easy installation and maintenance. Its SPDT configuration and robust design make it suitable for a wide variety of applications, from industrial and transportation to security. Its working principle is based on the actuation of two sets of contacts by an external force, which is greater than the adjustable actuation force. Additionally, it features a snap-action mechanism for reliable contact closure.
