## Long description

Karlik MWP-88 is a replacement switch mechanism intended for use in roller and venetian blind control switches. The unit supplies the electrical switching element only and is designed to be installed in standard in-wall switch housings. It supports a normally open (zwierny) contact arrangement and features mechanical retention to hold the switch position after actuation. The mechanism is suitable for residential and light commercial blind-control installations and requires a compatible frame, cover plate and actuator for complete assembly.
Advantages
The mechanism provides a compact, serviceable switching element that preserves familiar wiring and operation for roller or venetian blinds. Mechanical retention maintains the selected position without continued electrical activation, reducing actuator wear. Designed for straightforward replacement, the module fits common in-wall housings and can be installed without altering blind motor wiring when used with compatible components.
Suitable for
Replacement of faulty roller blind or venetian blind switch mechanisms in residential settings
Light commercial blind control points such as offices or small shops
Installations requiring a normally open contact with mechanical position retention
Projects where only the internal switching element needs replacement while retaining existing frames and covers
Key specifications
Contact type: normally open (zwierny)
Retention: mechanical position holding
Form factor: in-wall switch mechanism (module only, requires frame/cover/actuator)
Intended load: suitable for typical blind control circuits (motor control)
Application environment: indoor residential and light commercial use
How to use
Before installation, disconnect mains power and verify that the existing switch cavity and wiring are compatible with the replacement mechanism. Remove the old mechanism following standard safety procedures and wire the new mechanism according to the original terminal layout and local electrical regulations. Insert the module into the in-wall housing, secure it, and attach the compatible frame, cover plate and actuator. Restore power and test the operation of the roller or venetian blind to confirm correct switching and mechanical retention.
Usage recommendations
Use only compatible frames, cover plates and actuators from the same or compatible product series to ensure secure mounting and correct actuation. Verify electrical ratings and wiring before installation, and engage a qualified electrician for installations involving unfamiliar wiring or non-standard housings.
