2.2 Ledningsinstruktioner

The TM-1703 switch features three screw terminals: COM (Common), NO (Normally Open), and NC (Normally Closed). Refer to Figure 2 for terminal identification.

1. Afbryd strømmen: Before making any electrical connections, ensure that the power supply to the circuit is completely disconnected.
2. Identificer terminaler: Locate the COM, NO, and NC terminals on the switch.
3. Connect Common (COM): Connect the common wire from your control circuit to the COM terminal.
4. Connect Normally Open (NO): If you require the circuit to be closed when the switch is actuated (lever pressed), connect your load or signal wire to the NO terminal.
5. Connect Normally Closed (NC): If you require the circuit to be closed when the switch is NOT actuated (lever released), connect your load or signal wire to the NC terminal.
6. Sikre forbindelser: Ensure all wires are stripped to the appropriate length and securely fastened under the screw terminals to prevent loose connections and potential hazards.

Caution: Incorrect wiring can damage the switch or connected equipment. If you are unsure, consult a qualified electrician.

3. Betjening af kontakten

The uxcell TM-1703 is an automatic switch designed to change its contact state based on the physical actuation of its roller lever.

3.1 Grundlæggende betjening

• When the roller lever is in its normal, unactuated position, the circuit between COM and NC is closed, and the circuit between COM and NO is open.
• When an external force (e.g., a moving part of a machine) presses the roller lever, the internal contacts switch state. The circuit between COM and NC opens, and the circuit between COM and NO closes.
• Upon release of the roller lever, the switch returns to its original state.
