Jung 4008 TSM Módulo de botão, 1 polo, 250 V AC, 10 A, terminais de parafuso, encastrar, branco

Electricians and building technicians often need a reliable momentary-contact switch for flush-mounted installations in residential and commercial buildings. The Jung 4008 TSM push-button switch module fits this role perfectly, offering a 1-pole normally-open contact rated for 250 V AC and 10 A. It is compatible with Jung AS, A, CD, and LS series covers and rockers, allowing seamless integration into existing designs. The module features screw terminals for solid conductors up to 2.5 mm² and a compact installation depth of approximately 32 mm. Its thermoplastic body in white ensures durability and a clean look behind the cover plate. With an IP20 protection rating when installed correctly, it is suitable for dry indoor environments. The module operates at 50/60 Hz and can switch ohmic, inductive, or capacitive loads, making it versatile for lighting, bell, or control circuits. It is designed for flush-mounted (Unterputz) installation, providing a neat finish with compatible Jung frames.

Why choose it

The Jung 4008 TSM module is engineered for reliability and ease of installation. Its screw terminals provide a secure connection, and the compact depth allows it to fit in standard flush-mounted boxes. The momentary contact function is ideal for applications where a brief signal is needed, such as doorbells, staircase lighting timers, or control impulses. The module's compatibility with multiple Jung cover series gives flexibility in design, and its robust thermoplastic construction ensures long service life. With a wide operating temperature range and high humidity tolerance, it performs consistently in typical indoor environments.

Ideal use cases

• Doorbell push buttons in residential buildings
• Staircase lighting timer activation
• Control impulses for automation systems
• Momentary switching of lighting or small loads
• Integration into Jung AS, A, CD, or LS series installations

Good to know

The module is supplied as a bare insert without a cover plate or rocker; these must be ordered separately from the compatible Jung series. Installation should be performed by a qualified electrician, and the IP20 rating means it is intended for indoor use only, protected from moisture and dust. The screw terminals accept solid conductors up to 2.5 mm², and the module is suitable for switching ohmic, inductive, or capacitive loads up to 10 A. Always ensure the circuit is de-energized before installation.
