LEFOO / Mechanical Pressure Switches

LEFOO LF08M Manual-Reset Safety Pressure Switch has a manufacturer-defined reset mechanism, process and electrical operating envelope; this profile adds selection precautions rather than simply restating its product catalog.

Engineer the right device and order variant

Reset behaviourManual-reset protective switch, different from LF08D automatic-reset; verify human intervention and lockout logic
Pressure selection0.02–6.5 MPa; tolerances widen from ±0.03MPa at 0.2–0.6 MPa to ±0.25MPa at 5.0–6.5MPa
Electrical and ingress24–250VAC 0.02–6A, 8–36VDC 0.02–3A; maker IP67 with approved assembly
Temperature envelopeLow-pressure ambient −40…+65°C and media −40…+80°C; high-pressure ambient −40…+120°C and media −40…+135°C
Original order exampleLF08M-1 01C-0.2-0.3MPa (maker: ON 0.2MPa, OFF 0.3MPa); verify contact normal state and manual-reset sequence
Safety evidence LF08-series TÜV SÜD N8A 111343 0009 only names LF08, LF08D and LF08H, not LF08M.

Independent selection notes

Before ordering, confirm whether the control action is automatic or manual reset, normal circuit state, switch and reset points, minimum differential, proof and burst pressure, contact rating for the actual inductive load, wetted-media compatibility, final cable/connector ingress classification and ambient/medium temperature. None of these parameters should be taken from a different LF08 or LF20 sibling model.

LF08M — manual reset requires human intervention

The LF08M’s manual-reset function is a deliberate distinction from automatic LF08D restart behavior. Verify what over/underpressure event latches the contact, the actual reset-button access and any required operator inspection before returning a compressor to service. Manual reset alone does not make the product an independently certified safety limit. The installed pressure range, proof rating and contact rating must still be checked against machine requirements.
