Rocker Switches:M2013TJW01-FH-4A-CF Application Field and Working Principle

Rocker switches are mechanical devices used to toggle an electrical circuit and is often constructed of two plastic parts, one of which includes two or more spring loaded contact levers. Unlike a traditional toggle switch, the plastic part is held to the board by two posts, often called "rockers". When pressed, the rockers move, pushing the contact levers, opening or closing the circuit.

M2013TJW01-FH-4A-CF is a popular rocker switch designed for major applications in automotive, medical, industrial, and household appliances. This type of switch has a silver-plated contact that ensures reliable low-resistance contact and has a break-before-make contact mechanism.

This particular switch has a 4-position right-angle lever designed to prevent the contact levers from coming out of the contact closure. Besides the switch has a white thermoplastic body with contact separators that prevent shock. The rated voltage is 250 V and the operating temperature ranges from -25 to +105 °C. The mounting screws are 4.2mm x 0.8 mm.

Working Principle

The working principle of the M2013TJW01-FH-4A-CF rocker switch is similar to that of any other rocker switch. When the rocker is pressed, the switch completes the circuit, allowing current to flow through the contacts. When the rocker is released, the switch opens the circuit and breaks the flow of current.

The inner workings of rocker switches involve contact levers. The contact levers are spring-loaded and when the switch is pressed, they move and lift the contact levers out of their neutral positions, making a contact with the electrical terminals in the circuit board. The switch must be in the off position in order for the contact levers to go back to their neutral positions.

When the switch fails, it does so in an open position and does not allow current to pass through the contacts. The most common cause for failure of the M2013TJW01-FH-4A-CF switch is due to oxidation of the contact levers. When the contact levers become oxidized, they become weak and unable to hold sufficient current, thus leading to switch failure.

Conclusion

The M2013TJW01-FH-4A-CF rocker switch is designed for major applications in automotive, medical, industrial, and household appliances. The silver-plated contact ensures reliable low-resistance contact and has a break-before-make contact mechanism. The 4-position right-angle lever ensures that the contact levers will not come out of the contact closure. The switch is designed to withstand a range of temperatures and its rated voltage is 250 V.

The M2013TJW01-FH-4A-CF switch works by allowing current to pass through the contacts when the rocker is pressed and breaking the circuit when the rocker is released. The most common cause of failure for this switch is oxidation of the contact levers, which weakens the contacts and eventually cause circuit malfunction.
