Snap action and limit switches are electric switches made with a variety of actuation and positioning technologies. They are designed to recognize and respond to changes in position and motion of a device they are monitoring. The ZMCHM9T23R is one such switch, suited to applications like machines, appliances, and consumer electronic products.

The ZMCHM9T23R is a snap-acting, plug-in type limit switch. It is available in either a normally open (NO) or normally closed (NC) configuration, with a single-pole double throw (SPDT) configuration. It is characterized by a long service life, thanks to a robust housing and hermetic sealing that protect its internal mechanisms from temperatures up to 105°C and from dust, vibration and shock. The ZMCHM9T23R has an on-off ratio of 2.4, meaning it is able to switch off in 2/4 of a second.

The ZMCHM9T23R features an actuation type of snap-action, meaning it is actuated by the physical deformation of a mechanical element that “snaps” from one configuration to another when it is subjected to the necessary physical force. This makes the ZMCHM9T23R ideal for use in applications requiring frequent and swift switching action, such as in motor starters and elevators. It is also an ideal choice for a variety of consumer electronic products such as washing machines and refrigerators.

The ZMCHM9T23R is operated through an external mechanical actuator. When pressure is applied to the actuator, it snaps, which causes the contacts to change state. This actuation mechanism ensures that the switch operates reliably, quickly, and accurately, with a contact bounce of less than 0.2 milliseconds. The switch can be mounted easily without the need of tools or additional hardware thanks to the designed-in mounting flanges, and it is certified to UL, CSA, and EN standards.

The ZMCHM9T23R features a 13.5 mm contact gap and is equipped with 2 normally-open, (NO) contacts. The NO contacts are operated by a roller-level that is activated when pressure is applied to the actuator. This is beneficial for applications that require a two-wire configuration and frequent on-off switching.

The ZMCHM9T23R has a maximum operating voltage of 250V and a current rate of 4A, making it suitable for most typical applications. The model also offers a range of other features, including an adjustable operating force and a maximum opening angle of 40 degrees.

In summary, the ZMCHM9T23R is a snap-acting, plug-in type limit switch designed to offer increased performance and reliability. Its robust housing and hermetic sealing protect it from temperatures up to 105°C and from dust, vibration, and shock. It is certified to UL, CSA, and EN standards and is suitable for both industrial and consumer electronic applications requiring swift and frequent switching action.
