Switching timer Ospel Z-1R/m/40 — mechanical time switch model Z-1R/m/40

Ospel Z-1R/m/40 is a mechanical switching timer intended for scheduled on/off control of electrical circuits. The Z-1R/m/40 model combines manual override with automatic time switching, enabling straightforward scheduling of lighting and other resistive or inductive loads in domestic and light commercial installations. The device is designed for flush mounting in standard round canisters with a 60 mm diameter and fits systems where a simple, reliable mechanical time switch is required.

Advantages

The mechanical construction offers predictable operation without need for a separate power supply or software updates, and the manual control allows immediate switching when required. The compact design and standard mounting dimensions simplify installation in existing switchboards or wall boxes. Durability and uncomplicated mechanics make this timer suitable for applications where long service life and low maintenance are priorities.

Suitable for

• Timed control of indoor lighting in homes and apartments
• Basic scheduling of corridor, stairwell, or entrance lights in small commercial buildings
• On/off control of simple resistive loads such as heaters or fans (within device ratings)
• Retrofit installations using round canisters with 60 mm diameter

Key specifications

• Mechanical time switch with combined manual and automatic operation
• Flush-mount design for 60 mm round canister installation
• Intended for control of lighting and similar electrical loads
• Mechanical timing mechanism providing repeatable on/off intervals
• Compact form factor suitable for standard domestic and light commercial switchboxes

How to use

Install the timer in a compatible 60 mm round canister following local electrical regulations and ensuring power is isolated before wiring. Configure the mechanical time segments or settings according to the required schedule and use the manual override to switch the load immediately when needed. After installation, restore power and verify correct operation by testing the automatic cycle and manual control. If the unit is used with inductive loads, confirm load compatibility with the device specifications prior to connection.

Usage recommendations

Use the timer within the recommended electrical load limits and in dry indoor environments. Periodically check mechanical settings and contacts for wear if the device is used in frequent switching applications. For safety, have installation and any replacement work performed by a qualified electrician and confirm compatibility with the existing electrical installation and load types.
