The relay is intended to match the original relay’s role in call handling and control switching without altering the phone’s electrical behaviour when correctly installed.

Advantages

The relay provides a direct replacement for the original switching element in the ISH1030, preserving the telephone’s intended signal routing and mechanical switching performance. Its compatibility reduces diagnostic time during repairs and helps avoid the need for full-board replacement. The part is compact and designed for integration into the telephone’s existing mounting and connector layout, enabling straightforward restoration of call and control functions.

Suitable for

• Repairing TECHNISAT ISH1030 telephones
• Routine maintenance and refurbishment of ISH1030 units
• Stocking as a spare part for service workshops

Key specifications

• Function: electromechanical switching relay for telephone circuit applications
• Form factor: compact relay module suitable for in-device replacement
• Interface: designed to match the ISH1030 telephone’s relay footprint and connector arrangement
• Operating role: call switching and control signal routing within the telephone

How to use

Switch off and disconnect the telephone from power and line connections before beginning any repair. Access the internal PCB following the manufacturer’s service procedures and identify the relay location on the ISH1030 board.
