Why Construction Sites Require Paddle Safety Switches — Top Makita Angle Grinder Picks
On a construction site, the switch on your angle grinder isn't just a convenience feature — it's a safety mechanism. A paddle safety switch (also called a deadman switch) requires continuous pressure to keep the grinder running, so the disc stops the moment the operator lets go, whether from fatigue, a slip, or an unexpected kickback. This is why many site safety policies now require paddle-switch grinders over standard slide or trigger switches.
Why Paddle Switches Matter On-Site
Standard slide switches can lock the grinder in the "on" position, meaning the disc keeps spinning even if the tool is dropped or control is lost. A paddle switch removes that risk — the grinder only runs while the operator is actively gripping and pressing the paddle, cutting out immediately otherwise. Combined with anti-restart protection (which prevents the grinder from firing back up automatically after a power interruption), this is now considered baseline safety equipment on most job sites.
